To all whom traag/concern: f- Be it known that-I, OTTO M. DU BRAU, a I, residing at Baltimore, vState of Maryland, have inventcertain new and useful Improvements iny of vwhich the following is a specification, refverencebeing had therein to the accompany- ,ing drawing. Y

` This invention relates to improvements in 4the art of radiators 'and lizsforitsobject the capable of collecting the dust carried by the air anil` 'circuthrough the radiator under. normal working conditions, vExperience has shown that as anincident to the circulation of' air throughout a/room heated by vas ystem involving the use ofiadiators, the dirt and illisnaccumulations on the radiator are' picked up by the air and deposited onthe ceiling or in the corners adjacent to This isobjectionmore so, Where the ablein any case but far .Y f. ,-wallsare of arelatively expensive decorated type.

` Y y improvements overcome the objectlons attachment jwardly-therefrom vas heated through a dust collecting medium to purify the air as vit .condition and spreads -throughout the room. 'i 1 The invention comprehends an attachment l A knock-down nature,

comprising side and front'and rear panelsf anda `top section, adapted-when assembled in operative position toleave a lower portion ofthe front of 40 the radiator exposed for direct admission-of g conveniently of a the air, but envelopingth'e ends, upper portion of the front, rear an "tOp of the radia-A Vvtor to compel,i ,the Heated and dust or dirt- 'f laden air. to pass through a filteringV or screening mean-s capable of relieving the air of the objectionable particles borne thereby, prior'to the liberationofthe air thus puried into the room, the result being the elimination of unsightly or soiling .accumulations onthe walls or ceiling of, the room as well as purifying` the air for the consumption of thelroom'j occupants. ,f In .the accompanying drawings forming parthe'reof, I have illustrated the preferred '55 embodiment of niy inyention and the details gtion hereinafter contained.

Each panel comprises Aan open frame F having the open interior thereof bridged or fragmentarily illustrated at G and onthe rear ofeach panel the desired filtering-devices are mounted. These filtering devices comprise what may be termed a primary filter H and an 'auxiliary Ailter J, the former being composed of-a relatively closely woven` cotton orsimilar'cloth capable of catching the larger particles of dirt carried by the air passing therethrough, and the latter being composed of a highly fibrous substance such .110
